HOG-SCRAPER.

Specification of Letters Patent.

Patented Feb. 3, 1920.

.to the accompanying drawings forming a part of this specification.

My invention recites to hog scrapers and has for its object theprovision of an impro "ed device of this character in w 111011 thedehairing of the animal is brought about more completely andefit'ectively and which likewise in its actuations is adapted morethoroughly to perform other functions in the cleaning of a hog, such asa more thorough cleansing of the skin and removal of the toe nails.

My invention more particularly is an improvement over the structuredisclosed in my (Jo-pending application Serial No. 168.234, filed May12, 1917.

In the preferred form of my invention, as disclosed herein, 1 provide aconveyor which loosely carries the animal through the machine, which inits passage through the machine is acted upon by sets of heater ordehairing elements. One of these sets of dehairing elements is soarranged that the individual beater elements thereof act upon thecarcass in a circularpath instead of by a sweeping striking movement asheretofore The preferred manner in which I bring this about is bymounting the beater elements '11 a transverse face to the axis ofrotation which axis points toward the carcase so that the carcass ispresented to a yieldable disk-like face of the beater which acts uponthe carcass in a circular path. I also provide suitable means forpreventing the carcass from wedging between the dehairing elements.

will describe this form which my invention may take more in detail byreferring to the accompanying drawings, in which Figure 1 a top or planView of a machine constructed in accordance with my invention ig. 2 is aside view thereof, certain portions being shown in section;

Fig. 3 is a sectional View on line 3-3 of Fig. 2;

r 1 a is continuatlon of the view shown in Fig. to illustrate the lefthand extremity of the machine.

Fig. 5 is an end view of two of the beater elements of the right handset of beater elements shown in Fig. 3;

Fig. 6 is a sectional view on line 66 of Fig. 5, and

Fig. 7 is a fragmentary sectional View of line 7-7 of Fi 5.

In the drawings I illustrate a framework 10 which is of suitableconstruction to support the various parts of the machine. This frameworkis mounted adjacent to a second framework 11 which is preferablyconstructed in the form of a tank from which the carcasses are conveyedto the machine proper, as carried upon the framework 10. An endlessconveyor 12 extends from the tank 11 upwardly as shown more clearly inFig. i, and is then maintained substantially horizontally throughout theframework 10. The tension of the conveyor is suitably regulated bysupporting the axle 13 upon which sprockets 1% are mounted, in a lever15 which may be moved into its proper position by adjusting the nut 16.The conveyor is driven by means of the chain 17 which cooperates with asprocket wheel 18 mounted upon a shaft 19 which carries the sprockets 20for driving the conveyor. Power is derived from the power shaft 21 whichthrough the interposition of the worm 22 and worm wheel 23 drives thesprocket Qt. The conveyer is provided with suitable projections whichmay be made of angle iron, if desired, which assist in maintaining thecarcass in a given position upon the conveyer. The framework 10 likewisehas suitable provision to support a heater shaft 26 longitudinally ofthe conveyor, which beater shaft is driven by means of a chain 27, whichchain directly receives its power from the power shaft 21. (Figs. 13).The power shaft 21 likewise through the agency of a chain 28 drives thecountershaft 29 carrying the pulley 30 which operates the pump 31. riesa plurality of transversely placed beater shafts 32, 33, 34. and 35.These beater shafts are all driven through the agency of a chain 36, asclearly evident from Fig. 2, this chain 36 receiving its power from asprocket 37 which is driven through the agency of the The framework 10likewise carbevel gears 38, 39, the bevel gear 39 being carried directlyby the power shaft 21.

The longitudinal shaft 26 carries a plurality of sets of radiallydisposed beater elements to, each set consisting of a number or group ofheaters 41, as shown more clearly in Fig. 3. Each of the heaters 41-1 isflexible and carries dehairino; elements 42 designed to perform thefunction of dehairing the carcass. The beater elements are substantiallysimilar in form to those shown 111 my said co-pending application.

The transverse beater shafts 32, 33, 34: and 35, however, carry beaterelements 43, each having a group of heaters 44, as more clearly apparentfrom Figs. 5 and 6. These beater elements, as will be seen from afurther inspection of Figs. 3, 5, and 6, travel 1n a circular path uponthe carcass. The efi'ect of these elements 43 when rotating is topresent a yieldable disk-like face to the carcass as it is moved by.

The heaters that are in cooperative relation with the carcass effect acircular action upon that carcass as it is traveling past thoseparticular beater elements, thus performing more of a massaging thanstriking action as heretofore.

Therefore a higher peripheral speed is possible than where there is moreof a slap. With a greater slap, a high striking speed bruises the skin,loosening it from the fat. By working on a circular path, a greaterspeed is permissible thus getting a better cleansing action. Also thecircular path of travel massages the skin in many directions. The arms44: are provided with dehairing elements 46, the arms la being resilientto permit them to accon'imodate themselves to the body of the carcassand its extremities.

I find that I get a more thorough dehairing of the carcass by reason ofthe arrang ment of the beater elements L3 when acting in cooperationwith the beater elements d0. I find likewise that various otherfunctions are performed such as the removal of the toe nails in a morethorough and complete manner, and a more thorough cleansing of skineffected than has hitherto been possible. The effect of the rotativemoven'ient of the beater elements l3 upon a carcass of normal size is toneutralize any retarding influence that these beater elements may exert,that being due to the fact that the heater elements, as they rotatetravel in one direction and then in another. The direction of rotationof the beater elements 43 is shown by the arrows in Fig. 2 and the arrowin Fig. 3 shows the direction of rotation of the beater elements 40.

In order to prevent the carcass as it travels through the machine frombecoming wedged between two of the beater elements 43, I provide a guidestructure 47, shown more clearly in Figs. 5, 6, and 7. The guide 47 hasa protruding face l8 and sloping sides 49 which slope toward the disks50, whichdisks completely close the space back of the arms and uponwhich disks the said arms are mounted. These guides 4-7 thus prevent anytendency which there might be on the 1 t of the traveling carcass tobecome wedged between and adjoining disks 50. The continuit of travel ofthe carcass is thereby insured.

The carcasses travel through the machine i spaced relation and travelsubstantially at the speed of the conveyor, the'operations of the beaterelements being such as before that very little, if any, derangement ofthe spaced relationship is brought about.

Further .oie the action of the heaters i0 carried upon shaft 26 is toimpart a rolling motion to the hog as it is conveyed past the disk-likeheaters 43 so that these heaters 43 may act all around the carcass.

The action of the two sets of beater elements, respectively, the sets l0and 43, is such as not to materially influence the speed of the carcassas lb passing through the machine the rate of travel of the conveyer.

From what has been thus described the nature of my invention will beclear to those skilled in the art.
